Select your favorite species of flamingo. You may control-click (Windows) or command-click (Mac) to select more than one.

Multiple List Selections

Adding the multiple attribute to <select> allows the user to select more than one option. The user will need to hold down the ctrl or cmd key to select more than one option in the list, so you will need to add some explanatory text. If your list is long, it's a good idea to set a larger size so that multiple options are visible at the same time. This can save scrolling. As an alternative to multiple, consider using the checkbox input type.
